Mathematics
1 answer:
Oxana [17]4 years ago
5 0

Answer:

sin(-\theta)=\frac{3}{4}

Step-by-step explanation:

Given:

180°<θ<270° and sin(\theta)=-\frac{3}{4}

We know for any angle \theta,

sin(-\theta)=-sin(\theta)

∴sin(-\theta)=-(-\frac{3}{4})=\frac{3}{4}

Find the surface area of the shape below. Round your answer to two decimal places.
marin [14]

The surface area of the given shape is 285.01 ft²

<h3>Surface area of a cone </h3>

From the question, we are to calculate the surface area of the given shape.

The given shape in the diagram is a cone.

The surface area of a cone is given by the formula,

S = \pi r(r+l)

Where S is the surface area

r is the radius

and l is the slant height

First, we will calculate the slant height of the cone

l^{2}=9^{2} +5.6^{2} (<em>Pythagorean theorem</em>)

l^{2}=81+31.36

l^{2}=112.36

l}=\sqrt{112.36}

l=10.6 \ ft

∴ The slant height is 10.6 ft

Now, for the surface area

S = \pi \times 5.6(5.6+10.6)
S = \pi \times 5.6(16.2)

S = 90.72\pi  \ ft^{2}

S = 285.0053 \ ft^{2}

S ≅ 285.01 ft²

Hence, the surface area of the given shape is 285.01 ft²

Also this question tooo pleease, PS: what topic is this <br> Solve for x.
MrRissso [65]

This falls under geometry. The two labeled angles are congruent, which means the line segment between them (AD in the image) is a bisector of the angle at vertex A. Use the angle bisector theorem, which says that

\dfrac{BD}{DC}=\dfrac{AB}{AC}\iff\dfrac{12}{(5+9x)-12}=\dfrac{15}{25}

\dfrac{12}{9x-7}=\dfrac35

20=9x-7

x=3
